SHOULD I SELL CARBON CREDITS?

Increasing public attention to climate issues has amplified pressure on many industries to develop
‘climate neutral’ systems. A central goal of most ‘climate neutral’ strategies is for an entity to
achieve ‘net zero’ carbon emissions by reducing direct emissions of greenhouse gases (GHG) where
possible and seeking sources of carbon dioxide (CO
2
) emissions offsets (often called ‘carbon
credits’) to balance emissions that cannot be eliminated. These ‘offsets’ or ‘credits’ represent CO
2
being removed from the atmosphere and stored. Land-based carbon accumulation has long been
considered an essential element of climate mitigation strategies, and is increasingly viewed as a
potential source of purchasable credits for those seeking to offset emissions. This article describes
the foundational concepts of carbon trading, risks associated with entering a carbon credit contract,
and market considerations. Our goal is to inform ranchers so the best decisions can be made in an
emerging and uncertain enterprise.
CARBON CREDITS AND CARBON CREDIT TRADING
What is a ‘Carbon Credit’?
A carbon credit represents one metric ton (1,000 kg) of CO
2
or CO
2
equivalents removed from the
atmosphere. From an accounting perspective, if the atmosphere is the ‘account’, then a release of
CO
2
into the atmosphere is a ‘debit’ to that account, and removal of CO
2
from the atmosphere is a
‘credit’. A company may seek to reduce its emissions, but may not be able to completely eliminate
emissions. If they wish to achieve ‘net zero’ emissions, then they will seek ‘credits’ to their
atmospheric account that offset any remaining ‘debit’ amounts to balance the account. Sources of
carbon credits include those associated with natural processes that begin with photosynthesis of
plants. These are the focal point of this decision guide.
Creating a Carbon Credit
Plants effectively capture CO
2
from the atmosphere, and combine it with water through
photosynthesis to assemble it into carbohydrates. Some carbohydrates are translocated to the root
of the plant, and may be excreted or assimilated into the soil as organic matter that contains ‘soil
carbon’. This process transfers atmospheric carbon into soil carbon and is the basis of land-based
carbon credit generation (Figure 1). Generating a tradeable carbon credit requires measuring,
verifying, certifying, recording, and tracking the amount of carbon accumulated and retained in the
soil. Much like an exchange traded contract for a commodity, several entities have created
‘Standards’ for the generation of carbon credits.
